REE,
Here is a link to a dealer that has straw. I have an old Pearsall's color card with samples of the original gossamer colors. When Alec Jackson wanted to have straw reproduced;a mutual friend contacted me. He sent me a current Pearsall's embroidery color card and I informed them of the color which I thought most closely matched straw. For my effort I got to keep the color card and I got a box of a dozen Pearsall's straw gossamer reels. Bill
